Noise canceling 2.0?

Noise canceling headphones are a relatively modern innovation. With noise canceling, a microphone is utilized to pick up sound and then sound waves with opposite polarity (180° phase at all frequencies) are used to cancel much of the noise.

Knops work without batteries or any other form of electronics. A highly innovative system has been developed in which you can filter out a maximum of 21 decibel. Hear a siren coming in the distance? Cars honking at a busy roundabout? A train screeching into the station? Just turn up your Knops to dampen these sounds to a maximum of 21 decibels. It is as simple as that.


4 Filter settings

Whether you want some peace of mind in a busy train or want to save your ears from hearing damage, Knops’ four settings have you covered with decibel filtering from 0-21 dB.

We’re here to protect your ears

Knops are real lifesavers. Each pair of Knops has four steps. Adjust the Knops to step one and you will hear what you hear without plugs. The real kicker enters the stage when you switch to the other three steps. Step 2 will reduce the volume to filter the noise of a vibrant city, step 3 will adjust the volume to a live music setting, and step 4 will create a silent environment ideal for work. Four different modes for basically every audio situation.
